BACKGROUND

1. Technical Field

The present disclosure relates to a surgical device and, moreparticularly, to a powered rotating and/or articulating surgical devicehaving a controller supported on a handle having a cab-forwardconfiguration.

2. Background of Related Art

One type of surgical device is a linear clamping, cutting, and staplingdevice. Such a device may be employed in a surgical procedure to, forexample, resect a cancerous or anomalous tissue from a gastro-intestinaltract. A conventional linear clamping, cutting, and stapling device mayinclude a pistol grip-styled structure having an elongated shaft anddistal portion. The distal portion may include a scissors-styledgripping element. In this device, one member of the scissors-styledgripping element, such as the anvil portion, moves or pivots relative tothe overall structure, whereas the other member of the scissors-styledgripping element remains fixed relative to the overall structure. Theactuation of this gripping element may be controlled by a triggermaintained in or on the handle.

In addition to the scissors-styled gripping element, the distal portionof the stapling device may also include a stapling mechanism. The fixedmember of the gripping element may include a staple cartridge receivingregion and a mechanism for driving staples up, through clamped tissue,and against an anvil portion, thereby sealing the previously opened endof the tissue. The gripping elements may be integrally formed with theshaft or may be detachable such that various gripping, scissoring,and/or stapling elements may be interchangeable.

It may be necessary for a surgeon to move the opposing gripping elementsbetween various angles in order to position the desired tissue betweenthe opposing gripping elements. Thus, a need exists for improvements inthe maneuverability of clamping, cutting, and stapling devices.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In the figures and in the description that follows, in which likereference numerals identify similar or identical elements, the term“proximal” will refer to the end of the apparatus which is closest tothe operator during use, while the term “distal” will refer to the endwhich is farthest from the operator, as is traditional.

Referring to FIGS. 1A and 1B, a perspective view of a surgical devicehaving a controller, in accordance with the present disclosure ispresented.

In FIGS. 1A and 1B, there is shown a surgical device 800 that may beconfigured to stand alone, e.g., that includes various motors, driveshafts, control systems, etc., in an integral arrangement such thatattachment to a separate electro-mechanical surgical system may beeliminated. Such an arrangement may include the advantage that surgicaldevice 800 may not be connected prior to use to a separately-disposeddrive system. Surgical device 800 may be configured so as to beparticularly well-suited for insertion into the body of a patient, e.g.,via a cannula (not shown). Surgical device 800 may be a clamping,cutting, and stapling device.

Surgical device 800 may include an end effector or jaw portion 811 athat may be pivotably coupled to a shaft portion 811 b by a hingeportion 811 c. As seen in FIGS. 1A and 1B, shaft portion 811 b defines alongitudinal axis “D”. Jaw portion 811 a may include a first jaw 850having a distal end and a proximal end, and a second jaw 880 having adistal end and a proximal end. First jaw 850 and second jaw 880 may bepivotably coupled relative to each other at or near their respectiveproximal ends. As shown in FIGS. 1A and 1B, first jaw 850 and second jaw880 may be pivotable relative to each other about pivot axis “A”. Inthis arrangement, the jaws may be configured such that, upon opening andclosing of first jaw 850 relative to second jaw 880 and at points in themovement of first jaw 850 relative to second jaw 880, both first jaw 850and second jaw 880, e.g., their longitudinal axes remain within a plane.It should be understood, however, that surgical device 800 may insteadbe configured such that first jaw 850 and second jaw 880 may bepivotable relative to each other about a pivot axis that may be orienteddifferently from that shown in FIGS. 1A and 1B.

As mentioned above, jaw portion 811 a may be pivotably coupled to shaftportion 811 b by hinge portion 811 c. Specifically, jaw portion 811 amay be pivotable relative to shaft portion 811 b about a pivot axis “B”,which may be positioned at any location on or between jaw portion 811 aand shaft portion 811 b, and at any circumferential location relative tojaw portion 811 a and shaft portion 811 b. In the example embodimentshown, pivot axis B may be oriented vertically, and within the page. Inthis arrangement, jaw portion 811 a and shaft portion 811 b may beconfigured such that, upon articulation of jaw portion 811 a relative toshaft portion 811 b and at any point in the movement of jaw portion 811a relative to shaft portion 811 b, jaw portion 811 a and shaft portion811 b remain within a plane that may be perpendicular to pivot axis “B”.It should be recognized that, in other example embodiments, pivot axis“B” may have a different orientation, so as to enable jaw portion 811 ato pivot within a different plane. Jaw portion 811 a may be pivotable toand between any angles relative to shaft portion 811 b, such that jawportion 811 a may be selectively positioned as desired during use.

Furthermore, surgical device 800 may provide rotation of variouscomponents about a longitudinal axis of surgical device 800. Forexample, in various embodiments, jaw portion 811 a and/or shaft portion811 b may be rotatable relative to a handle 8103 (described inadditional detail below). Handle 8103 is attached to a proximal end ofshaft portion 811 b and may be rotatable along the longitudinal axis“D”. Shaft portion 811 b defines a distal portion 8101 a, to which jawportion 811 a is connected, and a proximal portion 8101 b, which isconnected to handle 8103.

Generally, handle 8103 may be grasped by an operator to operate surgicaldevice 800. Handle 8103 includes a proximal or base portion 8102, anintermediate portion 8104 extending from base portion 8102 and which mayinclude several finger-actuated control buttons 8107, 8108, and a distalor upper portion 8105 that is connected to shaft portion 811 b.

Reference may be made to U.S. Patent Publication 2009/0101692, theentire content of which is incorporated herein by reference for a moredetailed discussion of the construction and operation of jaw portion 811a and of surgical device 800.

In accordance with the present disclosure, handle 8103 is designed andconstructed so as to provide improved ergonomics and increased comfortto an operator. In this regard, intermediate portion 8104 of handle 8103may define a longitudinal axis “C” extending at an angle fromlongitudinal axis “D” defined by shaft portion 811 b. In particular, asseen in FIG. 1B, longitudinal axis “C” of intermediate portion 8104 ofhandle 8103 defines an angle of inclination of approximately 30°relative to longitudinal axis “D” defined by shaft portion 811 b.

FIGS. 1A and 1B also illustrates a controller 2000, which will bedescribed in more detail below with reference to FIGS. 2-4. Controller2000 functions to effectuate pivoting of jaw portion 811 a relative toshaft portion 811 b and to effectuate rotation, about longitudinal axis“D”, of jaw portion 811 a relative to shaft portion 811 b or of shaftportion 811 b relative to handle 8103.

Controller 2000 may include a first rotatable member 2100 (in the formof a wheel or dial) and a second rotatable member 2200 (in the form of awheel or dial). First rotatable member 2100 may be in operablecommunication with second rotatable member 2200 and may both besupported within a housing 2300. First rotatable member 2100 may be usedto control rotational movement of one or more components of surgicaldevice 800, whereas second rotatable member 2200 may be used to controllongitudinal/articulation/pivoting movement of the one or morecomponents of surgical device 800. For example, first rotatable member2100 may be used to pivot jaw portion 811 a about pivot axis “B”,whereas second rotatable member 2200 may be used to pivot jaw portion811 a about the longitudinal axis “D”. Thus, controller 2000 of surgicaldevice 800 may act as a rotation/articulation/pivot controller.

In an example embodiment, controller 2000 may be a dual wheel/dialconfiguration that may be suitably positioned, e.g., on a top or rearsurface of handle 8103, and sized so as to be actuatable by anoperator's thumb when the operator is holding handle 8103 in a pistolgrip fashion. As discussed above, it is contemplated that handle 8103may be designed and configured to provide more comfortable ergonomicsfor an operator when controller 2000 is located on a rear surface ofupper portion 8105 of handle 8103. It is contemplated, in an embodiment,that controller 2000 is disposed on handle 8103 so as to be aligned withthe longitudinal axis “D” of shaft portion 811 b. As seen in FIGS. 3Aand 3B, first rotatable member 2100 defines an axis of rotation “E” thatis substantially parallel with or is angled at an acute angle relativeto the longitudinal axis “D” defined by shaft portion 811 b.Additionally, as seen in FIGS. 3A and 3B, second rotatable member 2200defines an axis of rotation “F” that is substantially orthogonal to axisof rotation “E” of first rotatable member 2100. It is furthercontemplated that axis of rotation “E” of first rotatable member 2100and axis of rotation of “F” of second rotatable member 2200 intersectone another.

While a dual dial mechanism is shown for controller 2000, one skilled inthe art may contemplate a controller including a plurality of differentdials having a plurality of different shapes and sizes andinterconnected in a plurality of configurations or orientations on anyportion of surgical device 800. For example, in one embodimentcontroller 2000 may include at least a pair of dials, each defining anaxis of rotation, wherein the axes of rotation are substantiallyparallel to one another. In another embodiment, controller 2000 mayinclude at least a pair of concentric dials sharing a common axis ofrotation. It is further contemplated that controller 2000 may include aball supported in handle 8103 so as to rotate in any axis. In accordancewith another embodiment of the present disclosure, the first rotatablemember 2100 and the second rotatable member 2200 are nested within oneanother.

In use, rotation of first rotatable member 2100 in a clockwise directionmay effectuate rotation of jaw portion 811 a in a clockwise directionrelative to handle 8103, whereas rotation of first rotatable member 2100in a counter-clockwise direction may effectuate rotation of jaw portion811 a in a counter-clockwise direction relative to handle 8103.Similarly, rotation of second rotatable member 2200 in a clockwisedirection may effectuate pivoting of jaw portion 811 a in a firstdirection relative to handle 8103, whereas rotation of second rotatablemember 2200 in a counter-clockwise direction may effectuate pivoting ofjaw portion 811 a in a second direction relative to handle 8103, wherethe second direction is opposite the first direction.

In accordance with the present disclosure, it is contemplated that thespeed at which first rotatable member 2100 is rotated by the user oroperator may control the speed of rotation of jaw portion 811 a, whereasthe speed at which second rotatable member 2200 is rotated by the usermay control the speed of pivoting of jaw portion 811 a. It is furthercontemplated that an incremental rotation of first rotatable member 2100results in incremental rotation of jaw portion 811 a, and incrementalrotation of second rotatable member 2200 results in incremental pivotingof jaw portion 811 a. Stated differently, the speed or rotation of jawportion 811 a is commensurate to the speed of rotation of firstrotatable member 2100, and the speed of pivoting of jaw portion 811 a iscommensurate to the speed of rotation of second rotatable member 2200.In this manner, if an operator slowly rotates first and/or secondrotatable member 2100, 2200, jaw portion 811 a is slowly rotated and/orpivoted, and if an operator quickly rotates first and/or secondrotatable member 2100, 2200, jaw portion 811 a is quickly rotated and/orpivoted.

It is further contemplated that the rate at which first and/or secondrotatable member 2100, 2200 is/are rotated by an operator will vary ordetermine a degree of rotation and/or pivoting of jaw portion 811 a. Forexample, if an operator slowly rotates first and/or second rotatablemember 2100, 2200, jaw portion 811 a will rotate and/or pivot at aselected first rate (e.g., at a ratio of approximately 1:1). However, ifan operator quickly rotates first and/or second rotatable member 2100,2200, jaw portion 811 a will rotate and/or pivot at a selected secondrate, faster that the first rate, (e.g., at a ratio of approximately 2:1or 3:1 or any desired ratio greater than 1:1).

Referring to FIGS. 3A and 3B, exploded, perspective views of controller2000 of FIG. 2, in accordance with the present disclosure are presented.

As seen in FIGS. 3A and 3B, controller 2000 includes the first rotatablemember 2100 which is in the form of a rotation wheel 2110 supporting aplurality of magnets 2120. The plurality of magnets 2120 may besupported in/on rotation wheel 2110 with alternating north and southpoles around a perimeter of rotation wheel 2110. First rotatable member2100 of controller 2000 is rotatably supported on or about supporthousing 2300 and defines an axis of rotation “E”.

Controller 2000 further includes the second rotatable member 2200 whichis in the form of a rotation wheel 2210 supporting a plurality ofmagnets 2220. The plurality of magnets 2220 may be supported in/onrotation wheel 2210 with alternating north and south poles around aperimeter of rotation wheel 2210. Rotation wheel 2210 is rotatablysupported in/on support housing 2300 and defines an axis of rotation“F”. Controller 2000 further includes a base member 2400 operativelyassociated with rotation wheels 2110 and 2210.

Base member 2400 supports a plurality of Hall-Effect switches thereon.In particular, base member 2400 supports a first Hall-Effect switch 2130thereon such that first Hall-Effect switch 2130 is in magneticregistration with the plurality of magnets 2120 of rotation wheel 2110.Base member 2400 also supports a second Hall-Effect switch 2230 thereonsuch that second Hall-Effect switch 2230 is in magnetic registrationwith the plurality of magnets 2220 of rotation wheel 2210. WhileHall-Effect switches 2130 and 2230 are shown and described, it is withinthe scope of the present disclosure that controller 2000 may be providedwith optical sensors, illumination members in registration with theoptical sensors, and the like to accomplish the tasks and objectives ofthe Hall-Effect switches.

Controller 2000 includes a backing member 2500 that is configured tosupport the support housing 2300 and base member 2400 via fasteningmembers 2502. Controller 2000 further includes a ratchet member 2410, inthe form of a half-spring, supported on base member 2400. Ratchet member2410 is operatively engaged with a set of ratchet teeth 2111 formed onfirst rotatable member 2100 and a set of ratchet teeth 2211 formed onsecond rotatable member 2200. Ratchet member 2410 may provide a degreeof tactile and/or audible feedback to the user as either first and/orsecond rotatable members 2100 and/or 2200 is/are rotated in the form ofa clicking sound. For example, a series of nubs or ribs may be providedon a surface of rotation members 2100, 2200 and at least one nub may beprovided on a surface in juxtaposed relation to the nubs/ribs ofrotatable members 2100, 2200. It is further contemplated that theaudible sounds may be synthesized electronically according to any methodknown by one having skill in the art.

It is contemplated that controller 2000 may be provided with a visualindicator in the form of lights, LEDs, symbology, etc. that provides avisual indication to the operator of the direction of rotation/pivotingof jaw portion 811 a and/or when jaw portion 811 a is centered or in ahome position.

In operation, as first rotatable member 2100 is rotated, magnets 2120supported thereon are moved relative to first Hall-Effect switch 2130 toactuate first Hall-Effect switch 2130, which in turn causes a circuitboard (not shown) connected thereto to provide appropriate signals todrive components (e.g., a first drive shaft 1110 a, as illustrated inFIG. 1A) of surgical device 800 to effectuate rotation of jaw portion811 a. Additionally, as second rotatable member 2200 is rotated, magnets2220 supported thereon are moved relative to second Hall-Effect switch2230 to actuate second Hall-Effect switch 2230, which in turn causes thecircuit board (not shown) connected thereto to provide appropriatesignals to drive components (e.g., a second drive shaft 1110 b, asillustrated in FIG. 1A) of surgical device 800 to effectuate pivoting ofjaw portion 811 a.

Advantageously, rotation of first rotatable member 2100 in a firstdirection will effectuate rotation of jaw portion 811 a in a firstdirection and rotation of first rotatable member 2100 in a seconddirection will effectuate rotation of jaw portion 811 a in a seconddirection. Similarly, rotation of second rotatable member 2200 in afirst direction will effectuate pivoting of jaw portion 81 la in a firstdirection and rotation of second rotatable member 2200 in a seconddirection will effectuate pivoting of jaw portion 811 a in a seconddirection.

As mentioned above, controller 2000 is configured to include a firstrotatable member 2100 and a second rotatable member 2200, where secondwheel 2200 may be positioned at least partially within first rotatablemember 2100 and where second rotatable member 2200 may be orientedperpendicular with respect to first rotatable member 2100. Also,controller 2000 may include a first rotatable member 2100 and a secondrotatable member 2200, where first rotatable member 2100 and secondrotatable member 2200 may be permitted to be operated concurrently.However, it is contemplated that first rotatable member 2100 may belocked when second rotatable member 2200 is operated and vise versa.

Referring to FIG. 4, a perspective, rear view of a surgical device 800incorporating controller 2000, in accordance with the presentdisclosure, is presented wherein the surgical device has a cab-forwardstyle configuration.
